请问一下: 现在做spark 与hive整合的时候,需要maven 打包jar 出现错误。eclipse --> maven build 报错:

1.找到 file--》project structure ---》Modules --->Sources ---> Language level 改为 7.0就ok了。
2.你的spark版本是多少的,我记得spark1.6.0之后就要开始用jdk1.7+了

spark版本是cdh版的1.5.1 。用的是eclipse呀,没有那个project structure选项。不过现在解决啦。谢谢。是因为同一个项目下另外一个有问题,是因为不能同时catch 多个异常,移除了那个有问题的类就可以正常打包了。

是需要讲解详细的整合过程,还是说介绍一下编译打包的过程呢?
